The correct answer is: None of the above.
Personnel Administration Data systems, personnel planning data systems and the payroll system are all used to manage employee data. However, they do not all perform the same functions.
Personnel Administration Data systems are used to store and manage employee information, such as name, address, contact information, job title, and salary. They can also be used to track employee performance and attendance.
Personnel planning data systems are used to forecast future staffing needs and to develop recruitment and retention strategies. They can also be used to track employee turnover and to identify areas where there is a need for training or development.
The payroll system is used to calculate and process employee paychecks. It can also be used to track employee time and attendance, and to generate reports on payroll costs.
Therefore, none of the options listed in the question are correct.
